can you email me the name of the vendor privately? ([EMAIL PROTECTED])
also, does anyone know if other vendors do this properly, I would expect that
its pretty common practice to do this. I guess you may not notice the problem
until you get a server pretty heavilly loaded up and it needs to start
passivating objects from memory. It wouldnt be fun to find out this was
happening late in volume testing.
